CONTINUOUS-BURNING KILN FOR BRICKS OR OTHER ARTICLES.

SPECIFICATION forming part of Letters Patent No. 673,231, dated April30, 1901.

Application filed March 16,1900. Serial No. 8,965. (No model.)

To ctZZ whmn it may concern.-

Be it known that I, ADAM ADAMS, a subject of the Queen of Great Britain,residing at Old Fletton, in the county of Huntingdon, England, haveinvented certain new and useful Improvements in and Connected withContinuous-Burning Kilns for Bricks or other Articles, of which thefollowing is a fu1l,clear, and exact description, and for which I havemade application for a patent in Great Brillain, dated the 29th ofAugust, 1899.

This invention relates to improvements in that class of kilns known asI-Ioifmans kilns, and has for its object an improved construction andarrangement of parts whereby the waste heat from each chamber or ovencan be utilized to its full extent by conveying the burned gases to achamber or oven of green bricks to perform the process of watersmokingand whereby steam is generated in a series of boilers, some of which arebeing continually heated, while others for a time are out of use. Thissteam may be employed to obtain power for making the bricks.

In carrying my invention into effect I construct a number of chambers orovens in any suitable order and connected with each other and by meansof flues with a common smoke chamber or chambers leading to the chimneyor smoke-stack, as hereinafter described.

I will describe my invention by the aid of the accompanying drawings, inwhich- Figure 1 is a quarter-plan drawn on the line 1 1 of Fig. 4. Fig.2 is a quarter-plan drawn on the line 2 2 of Fig. 4. Fig. 3 is a halflongitudinal section drawn on the line 3 3 of Fig. 2; and Fig. 4 is across-section of the entire kiln, one half being drawn through thefiuef, Fig. 1, and the other half through the fiue 6. Fig. 5 is asectional view, and Fig. 6 is a part elevation showing a modification.

a a are the various ovens or chambers. Over these chambers or ovens arearranged a series of horizontal pipes or fines b b, through which thegases are conveyed along the top of the kiln. Each chamber or oven a iscapable of being connected and disconnected with a series of thesehorizontal pipes or fiues b by suitable valves 0, placed invalve-chambers 0 formed above an opening ct* in the roof' of thechambers or ovens a and communicating with the horizontal pipes or fluesb,

and these horizontal pipes or fines b are provided with other valves 0',placed in valvechambers 0 formed at the junction of the horizontal pipesor fines b with the vertical pipes or fiues d, by which they can beconnected and disconnected with the upper parts of vertical pipes orflues d, constructed or built Within the walls a, dividing thechambersor ovens a, and in order that these valves may be operated fromthe roof of the kiln the tops of the valve-chambers c c are closed bycovers a, fitting on seats 0 The lower ends of these vertical pipes orfines (1 open into hot-air fines e, formed along one side and below thefloor a of each chamber or oven a and extending from end to end thereof.The floors a of the chambers or ovens 0., along one side thereof, haveopenings a distributed along the length thereof, communicating with saidhot-air does 6. Along the opposite side of these floors are formed anumber of openings a, communicating with fiues f for the waste gases,constructed below such floors 0?, and such latter fiues lead tothevertical passages f, communicating with the smoke chamber or chambersg, with which they may be connected or disconnected by suitable valvesg. There are also openings (1 in the floors of the corner ovens orchambers to serve the same purpose as the openings a The smoke-chambersg lead into the flue or chimney w. 0, represents the outer walls of thekiln, and a represents the door ways or entrances to the chambers orovens 0..

Thus the fire is continually traveling around the kiln in one direction.Passages a for the fire are formed one at each end and at intervalsalong the walls a between the chambers or ovens a, and the inner ends a,of the lat- .ter are bayed to resist the bulging of the 9 being alsoopened. The hot gases are thus drawn by the draft of the chimney a: fromthe upper part of the burning chambers or ovens a, through the openinga*, along the pipes b at the top of the kiln, then down the verticalpipes or fines d, whence they aredelivered at the bottom of the chamberor oven 0. required to be water-smoked. When the water-smoking in achamber or oven at is nearly completed, the hot gases are Shut ofitherefrom, and the main fire is drawn in through the passages of in theside walls a, and the burning completed in the usual manner. The processabove described is repeated with each chamber a as the fire travelsaround the kiln, thus producing bricks or other articles evenly driedand burned. The Whole arrangement can be worked from the top of thekiln.

I arrange a series of boilers h, resting on piers or supports a inspaces a formed in the roofs a of the chambers or ovens a, each of suchboilers it being provided with the usual fittingsnamely, safety-valve h,water-gage 7L water-cocks h manhole h blowout cocks 71 and steam-gage hValves 2' 2" enable the boilers to be connected and disconnected withcommon feed and steam pipes j and k, and valves 1? enable parts of thecommon steam-pipe to be cut off. As the fire travels around the kilnthere are always a certain number of chambers or ovens a hot, so that atany given time a certain number of the boilers are being heated. Thevalves 11 2' are so arranged that, say, any two adjacent boilers h canbe cut off for inspection or repairs at one time. in pairs adjacent toeach other.

In the'modification shown at Fig. 5 the hotair fines are dispensed with,and the lower parts of the vertical pipes or fines d are built inbrickwork, leaving small openings 0, be-- tween the joints of the latterand a larger opening a at the floor-level to break up the heat intosmall currents on its way down said pipes or fines d. v

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a continuous-burning kiln, the combination of a series of ovens orchambers, holes in the roofs of such chambers through which smudge orother fuel is fed to assist burning; bayed inner ends to such ovens orchambers; a series of horizontal pipes or fines above said ovens orchambers; a series of vertical downdraft-fines within the walls dividingthe chambers or ovens; hot-air fines along one side and below the floorsof the ovens or chambers and communicating with said verticaldowndraft-fines; openings in and along one side of the oven-floorscommunicating with said hot-airflues; valves to connect and disconnectthe horizontal pipes or fines with the ovens or-chambers; valves toconnect and The boilers are arranged disconnect the horizontal andvertical pipes or fines; main outlet-fines below the ovenfloors on theside opposite to that of the vertical pipes or fines; openings along oneside of the oven-floors communicating with such outlet=fiues; verticalpassages connecting the main outlet-fines with the smokechamber; valvesarranged on the top of the vertical passages; a smoke-chan1ber intowhich such vertical passages open, and a smoke-stack -0'r chimney intowhich the smoke-chamber opens, substantially as herein set forth.

2. In a continuous-burning kiln, the combination of a series of ovens orchambers; parallel sides to such chambers; passages for the fire in thewalls; holes in the roof of such chambers, through which fuel is fed;outletopenings in the roofs; valves to close said openings; valvechambers in which the valves are situated; horizontal pipes or finesabove said ovens communicating with the valve-chambers; verticaldowndraft-fines arranged in the walls dividing the chambers or ovens;valves to connect and disconnect the vertical downdraft-fines with thehorizontal fines; openings communicating between the ovens or chambersand the downdraft-fines; main outlet-fines below the oven-floors on theside opposite to the vertical downdraft-pipes; openings along one sideof the oven-floors v communicating with such outlet-fines; verticalpassages connecting the main outlet-fines with the smoke-chamber valvesarranged on top of the vertical passages; the walls of suchsmoke-chamber having parallel interior sides and bayed external portionsforming the backs or inner ends of the ovens; and a smoke-stack orchimney into which the smokechamber opens, substantially as set forth.

3. In a continuous-burning kiln, the combination of a series of ovens orchambers; parallel straight sides to such ovens; arched roofs to suchovens; boilers arranged to form part of the roofs and supported partlyby the arches; piers in such ovens to partly support f the boilers;holes in the roofs of such ovens through which fuel is fed; mainoutlet-fines below the oven-floors; openings along one side of theoven-floors communicating with such outletfines; a smoke chamber intowhich such outlet-fines open; parallel interior sides to thesmoke-chamber walls; exterior bayed portions to such Walls forming thebacks or inner ends of the ovens; and a :smoke stack or chimney intowhich such smoke-chamber opens, substantially as set the smoke-chamberwalls; bayed exterior portions to such walls forming the backs or innerends of the ovens; and a smoke-stack r5 into which the smoke-chamberopens, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
